find the least common multiple of 20 and 25
Marie noticed that she was eating 2100 calories per day she began a diet and limited herself to 1300 calories per day. What is the percent of decrease? Round to the nearest percent.
Answer:
decrease of 38% (to nearest percent)
Step-by-step explanation:
Percent change = [ (difference between final and initial value) ÷ initial value] x 100
⇒ percent change = [(2100 - 1300) ÷ 2100] × 100 = 38% (to nearest percent)
Which percent is equal to 0.3
A 0.003%
B 0.03%
C 3%
D 30%
pls answer fast
Answer:
D. 30%
Step-by-step explanation:
Answer:
D) 30%
Step-by-step explanation:
→ a = 0.3
General formula,
→ a × 100 = %
Let's solve the problem,
→ 0.3 × 100
→ 30%
Thus, option (D) is answer.

Alternate exterior angles are formed by a transversal intersecting two parallel lines, therefore, your alternate exterior angles are <1 and <5.
Your alternate interior angles are <2 and <6/ <3 and <7.
Corresponding angles are formed when two parallel lines are intersected by a transversal. (<1 and <3)
Vertical angles are formed when two lines intersect each other. Therefore, <1 and <7 fall into this category.

Step-by-step explanation:
Half of 40 is 20 and luckily they already gave us how much she would earn if she worked 20 hours.
So all we have to do is multiply the amount of money she earned when she worked 20 hours by 2 to see how much she earned when she worked 40 hours.
20 hours:165 dollars or 20:165
20 x 2= 40 and 165x2=330
So if Monique worked 40 hours she would earn $330.

Answer:
A: Vertical angles are congruent, C is the midpoint of BE, and ∠B ≅ ∠E.
B: C is the midpoint of AD, BC ≅ EC, and Vertical angles are congruent.
C: I assume you cannot use CPCTC so AAS and ASA.
Step-by-step explanation:
A: Since vertical angles are congruent, the interior angles using point C of the triangles are congruent. If C is the midpoint of BE, BC ≅ EC. Draw the congruent parts based on the 3 statements with tick marks and you will see that you have two pairs of congruent angles with an included pair of congruent sides, so ASA applies.
B: If C is the midpoint of AD, AC ≅ DC. Since vertical angles are congruent, the interior angles using point C of the triangles are congruent. Draw the congruent parts based on the 3 statements with tick marks and you will see that you have two pairs of congruent sides with an included pair of congruent angles, so SAS applies.
C: ∠B ≅∠E and ∠A ≅∠D since these are pairs of alternate interior angles. Since vertical angles are congruent, the interior angles using point C of the triangles are congruent and it is given that AB ≅ DE. When making the appropriate marks, you will see that only AAS and ASA can be used without CPCTC.

Answer:
A
Step-by-step explanation:
The initial amount is 64, so that would be the y-intercept.
Each piece of wood, x, is [tex]6\frac{1}{4}[/tex] inches long, so x pieces would be [tex]6\frac{1}{4}x[/tex] pieces long.
Because you're subtracting the length of the pieces from the total length, you would subtract [tex]6\frac{1}{4}x[/tex] from 64.

W=A/3 What does A equal?
Answer:
[tex]\huge\boxed{\bf\:A = 3W}[/tex]
Step-by-step explanation:
If [tex]\sf\:W = \frac { A } { 3 }[/tex], then A = ?
At first let's shift the the term 'W' to the LHS & A/3 to the RHS to bring the equation in the standard form.
[tex]\sf\:\frac{A}{3}=W[/tex]
Now, we know that, A/3 is the same as ⅓ A. Then,
[tex]\sf\:\frac{1}{3}A=W[/tex]
By multiplting both sides by 3..
[tex]\sf\:\frac{\frac{1}{3}A}{\frac{1}{3}}=\frac{W}{\frac{1}{3}} \\\sf\: A=\frac{W}{\frac{1}{3}}[/tex]
Divide [tex]\sf\:\frac{W}{\frac{1}{3}}[/tex] by its reciprocal.
[tex]\sf\:A=\frac{W}{\frac{1}{3}} \\ \sf\:A = \frac{3W}{1}\\[/tex]
So, the value of A is [tex]\downarrow[/tex]
[tex]\boxed{\bf\:A = 3W}[/tex]

Find the values of the coefficients b and c in the quadratic equation 3x2+bx+c if the sum and product of the roots of this equation are respectively 7/3 and 13/3.
Answer:
a = 3
b = -7
c = 13
Step-by-step explanation:
[tex]\sf{given \ equation: 3x^2+bx+c[/tex]
[tex]\sf{sum \ of \ roots :\sf\frac{7}{3}[/tex]
[tex]\sf{product \ of \ the \ roots:\frac{13}{3}[/tex]
a = 3b = bc = c[tex]\sf{sum \ of \ roots \ = -\dfrac{coefficient \of \ x}{coefficient \ of \ x^2} }[/tex]
[tex]\sf \frac{-b}{3} = \frac{7}{3}[/tex]
[tex]\sf b = \frac{-7*3}{3}[/tex]
[tex]\sf b =- 7[/tex]
[tex]\sf{product \ of \ roots \ = \dfrac{constant \ term}{coefficient \ of \ x^2} }[/tex]
[tex]\sf{\frac{c}{3} =\frac{13}{3}[/tex]
[tex]\sf c = \frac{13*3}{3}[/tex]
[tex]\sf c = 13[/tex]
Therefore found that a = 3, b = -7, c = 13
Answer:
b = -7
c = 13
Step-by-step explanation:
[tex]3x^2+bx+c[/tex]
[tex]\textsf{sum of roots}=\dfrac{-b}{a}\\\\\textsf{product of roots}=\dfrac{c}{a}[/tex]
[tex]\textsf{Given sum of roots}=\dfrac73:[/tex]
[tex]\implies \dfrac{-b}{a}=\dfrac73[/tex]
[tex]\implies a=3, b=-7[/tex]
[tex]\textsf{Given product of roots}=\dfrac{13}{3}:[/tex]
[tex]\implies \dfrac{c}{a}=\dfrac{13}{3}[/tex]
[tex]\implies a=3, c=13[/tex]
Therefore,
[tex]3x^2-7x+13[/tex]
NB: The actual calculated roots are imaginary numbers as the function [tex]f(x)=3x^2-7x+13[/tex] does not intercept the x-axis

Find a line that is perpendicular to y = 2/5x-1 that goes through (3,6)
Answer:
y = -5/2x + 27/2
Step-by-step explanation:
line formula is y = mx + b
perpendicular means number next to the x (slope or m) becomes a negative reciprocal
2/5x -> -5/2x
then use point slope formula
y - y1 = m (x - x1)
y - 6 = -5/2 (x - 3)
y - 6 = -5/2x + 15/2
y = -5/2x + 15/2 + 6
y = -5/2x + 15/2 + 12/2
y = -5/2x + 27/2

max is using a hose to fill an above ground swimming pool, which is shaped like a rectangular prism. the pool is 7meters long and 3 meters wide, and max plans to fill the pool with water 0.75 meters deep. the house flows at a rate of 2,250 liters, or 2.25 cubic meters, per hour.
how long does it take to fill the pool?
write your answer as a whole number or decimal. do not round.
Using the volume of the rectangular prism, it is found that it takes 7 hours to fill the pool.
What is the volume of a rectangular prism?The volume of a rectangular prism of dimensions l, w and h is given by the multiplication of it's dimensions, that is:
V = lwh.
In this problem, the dimensions in meters are: l = 7, w = 3, h = 0.75. Hence, the volume in cubic meters is:
V = lwh = 7(3)(0.75) = 15.75.
It fill 2.25 cubic meters per hour, hence, for 15.75 cubic meters, the time taken is:
15.75/2.25 = 7 hours.

parabola, circle, ellipse, or hyperbola.
a. parabola
c. hyperbola
b. ellipse
d. circle
Answer:
b. ellipse
Step-by-step explanation:
The squared terms have the same sign and different coefficients. That means the equation describes an ellipse.

Additional comment
both variables are highest degree 2:
coefficients have the same sign and magnitude: circle
coefficients have the same sign and different magnitude: ellipse
coefficients have different signs: hyperbola*
only one variable has highest degree 2:
